Add chunked responses and streaming of raw queries.
...
Refactored query engine to have different processing pipeline for raw queries. This enables queries that have a large offset to not keep everything in memory. It also makes it so that queries against raw data that have a limit will only p
rocess up to that limit and then bail out.
Raw data queries will only read up to a certain point in the map phase before yielding to the engine for further processing.

fix #2215 : allow keyword default to be unquoted

InfluxDB creates a default retention policy named "default". DEFAULT is
also a keyword in the language. This required double quoting "default"
in the ALTER RETENTION POLICY statement. This commit makes the parser
accept it unquoted for that one statement.

Fix issue with time buckets and improve performance
...
When the start time fell in the middle of a group by bucket, the times for all buckets would be off by the amount of that stat time. This fixes it so group by windows are always on the bucket. However, if the user specifies a start time in the middle of a bucket, the very first bucket will only have whatever data in it that is past the start time (so it'll be a partial)
Also fixed a performance bug where if someone issued a query like: `SELECT mean(value) FROM foo GROUP BY time(10s) LIMIT 3`. Previously, the engine would create emtpy values for every 10s window since 1970, then limit it afterwards. Now, it'll just create value holders for the 3 buckets we need.

fix #1799 : make scanner recognize regex
...
Change the regex delimiter from single quotes to back ticks (`) and make
the scanner recognize regex tokens.
Single quotes are used for string literals. Using a unique delimiter for
regular expression literals allows the scanner to recognize regular
expression tokens, which is inline with the way the rest of the
scanner / parser work.
